    3.运行第一个容器
    1. sudo docker run --name wgl_centos -i -t centos /bin/bash
    2. sudo docker rename oldername newname
     
          -i  保证容器中stdin是开启的，尽管我们并没有附着到容器中，是交互式shell的半边天；-t  是另一半边天，他告诉docker为要创建的容器分配一个伪tty终端。如要在命令行下创建一个我们能与之经行交互的容器，而不是一个运行后台服务的容器，这两个是基本的了。

    4.查看宿主机容器列表
    1. sudo docker ps -a #显示全部容器
    2. sudo docker ps -l #列出最后一个运行的容器，也可以--format进一步控制显示
    3. sudo docker ps -n x #显示最后x个容器。
    5.启动，停止容器
    1. sudo docker start（restart,stop） 容器ID(容器name)
    6，附着到容器上
    1. sudo docker attach 容器
    例如
    sudo docker start dreamy_knuth    先启动（启动后会沿用run命令时指定的参数运行）
    sudo docker attach dreamy_knuth 后附着到容器，【及进入交互界面】
    相当于
    sudo docker start dreamy_knuth 
    sudo docker exec -i -t dreamy_knuth  /bin.bash（可用于打开一个守护式容器）
     
    7，创建守护式容器
    1. sudo docker run --name wgl_centos_daemon -d centos /bin/sh -c "while true;do echo hello world;sleep 3;done"
    在后台运行，只返回容器ID。
    -d 在后台运行
     
    8.获取守护式容器的日志
    1. sudo docker logs 容器 #输出最后几条后返回
    2. sudo docker logs -f 容器 #监控日志
    3. sudo docker logs --tail 10 容器 #获取容器日志最后10条
    4. sudo docker logs --tail 0 -f 容器 #跟踪最新日志
    5. sudo docker logs -ft 容器 #监控日志+时间戳
     
    9.dockers日志驱动
    1. sudo docker run --log-driver="syslog" --name wgl_centos_daemon -d centos /bin/sh -c "while true;do echo hello world;sleep 3;done"
    --log-driver=
    syslog 将容器日志重新定向到Syslog,禁用dockers logs命令
    json-file 默认，用dockers logs命令查看
    none 禁用所有容器中的日志，禁用dockers logs命令
     
    10.查看容器进程
    1. sudo docker top wgl_centos_daemon
    11.docker统计信息
    1. sudo docker stats [容器1 容器2 容器3 ...]
     
    12.在容器内部运行进程
     
    后台式任务与交互式任务
     
    后台式任务
    1. sudo docker exec -d 53fc4852ce08 touch /opt/wgl.log # -u 为新启动的进程指定属主
    通过docker exec 后台命令，可维护，监控，管理正在运行的容器
     
    进入容器(不论是守护式还是交互式)的交互式界面
    1. sudo docker exec -it 53fc4852ce08 /bin/bash
     
    13，自动重启容器
    1. sudo docker run --restart=always --name wgl_centos_daemon -d centos /bin/sh -c "while true;do echo hello world;sleep 3;done"
    --restart会检查日期的退出代码
    always        不认退出代码是什么，都重启
    on-failure    退出代码非0才重启，还可以设置重启次数：--restart=on-failure：5
     
    14.深入容器，容器详情
    1. sudo docker inspect 容器
     
    1. [dwsoft@wgl ~]$ sudo docker inspect wgl_centos_daemon

    也可用-f或--format，查看选定的结果，可查看多个容器，多个结果。
     
     
    15，删除容器
    1. sudo docker rm 容器
    2. sudo docker rm -f 容器 #删除正在运行的容器
    3. sudo docker rm `sudo docker ps -a -q` # -q只返回容器ID
